Faccebbook hidden service

Facebbookk as hidden service is ridicoulus .
The principles when hidden services started was to keep client anonymous but also the server. The hidden website or the server in charge (i remeber the struggle on removing the real hostname responded to clients ehlo command while connecting to hidden smtpd servers) where forced to remove every single banner or pic leading to their real fqdn in real internet ,otherways there was no point in hidden services ,they were not hidden anymore.
that's said
